TECHNICAL FIELD

The present disclosure relates to the field of cameras. In particular, the present disclosure relates to an imaging device and a camera having a night vision mode.

BACKGROUND

In daily life, cameras are used more and more widely, and especially in order to prevent theft or for a monitoring purpose, home network cameras are also increasingly common these days. Cameras bring convenience to people's lives, but also have risks of exposing people's privacy.

In order to protect privacy, a camera having a privacy protection function as shown in FIG. 1 has been proposed in the prior art.

As shown in (A) of FIG. 1, when the camera works normally, a small baffle 1 made of an opaque material is located below lens L to expose lens L. As shown in (B) of FIG. 1, when privacy protection is required, the small baffle 1 is moved upward to block lens L. The small baffle 1 is separated from an infrared transmitting cover 2 in front of an infrared LED of the camera. This design results in an increase in the number of components, and destroys the integrity of the industrial design, thus affecting the aesthetic appearance of the camera.

In addition, as shown in (B) of FIG. 1, when the small baffle 1 blocks lens L of the camera, lens L cannot receive visible light from the outside, and the camera enters a night vision mode, i.e. the infrared LED of the camera would be automatically opened to emit infrared light to a person or article, etc. around the camera. However, since lens L has been blocked by the small baffle 1 made of an opaque material, infrared light reflected by the person or article, etc. outside cannot be received by lens L. In this case, light emitted from the infrared LED is completely wasted and would not play any role, which greatly reduces the lifespan of the infrared LED.

Moreover, in the camera shown in FIG. 1, although blocking lens L by means of the small baffle 1 may protect privacy to a certain extent, at this time, audio input is not cut off, and the privacy may still be exposed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

For better understanding of the solutions of the present disclosure by a person skilled in the art, the technical solutions of the embodiments of the present disclosure will be described in a clear and complete manner in conjunction with the drawings related to the embodiments of the present disclosure. Obviously, the following embodiments are merely a part of, rather than all of, the embodiments of the present disclosure, and based on these embodiments, a person skilled in the art may obtain the other embodiments without any creative effort, which also fall within the scope of the present disclosure.

According to an embodiment of the present disclosure, there is provided an imaging device. FIG. 2 is a block diagram of an imaging device according to an embodiment of the present disclosure.

Referring to FIG. 2, an imaging device 200 according to an embodiment of the present disclosure comprises a main body 201, a lens 202, at least one infrared LED 203, a control circuit 204, a switch 2041, and a baffle 205.

The main body 201 comprises a panel 2011, the main body 201 may be a housing of the imaging device 200, and the panel 2011 is provided in the housing.

The lens 202 is provided in the housing, is exposed from an opening on the panel 2011, and is configured to perform imaging according to received light.

The at least one infrared LED 203 is provided around the lens 202 and is exposed from the opening on the panel 2011. If the amount of visible light received by the lens 202 is less than a predetermined value, for example, in a dark environment, when the lens 202 cannot receive visible light at all or can only receive a small amount of visible light, the at least one infrared LED 203 may be controlled to emit infrared light to the outside. Infrared light emitted from the at least one infrared LED 203 may be reflected by an object, for example, a person or an article, within an imaging range of the imaging device, and the reflected infrared light is received by the lens 202, so that a black-and-white image may be generated.

The number of the at least one infrared LED 203 may be, for example, four, and four infrared LEDs are provided at equal intervals around the lens 202, however, the present disclosure is not limited thereto.

The control circuit 204 is provided in the housing of the imaging device 200, and may control imaging of the lens 202 and light emission of at least one infrared LED 203. For example, when the control circuit 204 is turned on, the lens 202 is allowed to image an object (for example, a person or an article) within an imaging range of the imaging device, and when the control circuit 204 is turned off, the lens 202 is prohibited from imaging an object within an imaging range of the imaging device; if the visible light received by the lens 202 is less than a predetermined value, for example, in cases where the lens 202 cannot receive visible light at all, when the control circuit 204 is turned on, the at least one infrared LED 203 is allowed to emit infrared light to the outside, and when the control circuit 204 is turned off, the at least one LED 203 is prohibited from emitting infrared light to the outside.

The switch 2041 is provided in the control circuit 204 for turning on the control circuit 204 or turning off the control circuit 204.

The baffle 205 is provided on the main body 201 to cover at least a portion of the panel 2011. The baffle 205 is made of an infrared transmitting material capable of transmitting infrared light. Infrared light emitted from the at least one infrared LED 203 may be transmitted through the baffle 205 to be emitted to the outside.

The baffle 205 is movable between a first position and a second position on the main body 201.

When the baffle 205 moves to the first position, the baffle 205 covers the at least one infrared LED 203 and exposes the lens 202. At this time, the baffle 205 triggers the switch 2041 to turn on the control circuit 204, so that the control circuit 204 controls the lens 202 and the at least one infrared LED 203 to work normally. For example, in cases where the control circuit 204 is turned on, if the lens 202 is capable of receiving an amount of visible light which is reflected by an object within an imaging range of the imaging device 200 and is greater than a predetermined value, the imaging device 200 is capable of acquiring a color image of the object ((for example, a person or an article)) within its imaging range, and if the amount of visible light received by the lens 202 is less than a predetermined value, the control circuit 204 controls the at least one infrared LED 203 to emit infrared light, infrared light emitted from the at least one infrared LED 203 irradiates the object within an imaging range of the imaging device 200, infrared light reflected by the object is received by the lens 202, and the imaging device 200 obtains a black-and-white image of the object within its imaging range.

The baffle 205 may be provided with a central opening at the central portion.

When the baffle 205 is in the first position, the lens 202 is exposed from the central opening of the baffle 205.

When the baffle 205 moves to the second position, the baffle 205 blocks the lens 202, for example, when the baffle 205 moves to the second position, the central opening of the baffle 205 is deviated from the lens 202, and the lens 202 thus is blocked by other portion of the baffle 205. At this time, the baffle 205 triggers the switch 2041 to cause the switch 2041 to turn off the control circuit 204. Since the control circuit 204 is turned off by the switch 2041, imaging of the lens 202 and light emission of the at least one infrared LED 203 are both prohibited, and the imaging device 200 stops working.

The imaging device 200 may also comprise an audio acquisition device (not shown in FIG. 2) for acquiring sound around the imaging device 200. The audio acquisition device is also controlled by the control circuit 204, for example, when the control circuit 204 is turned on, the audio acquisition device is allowed to acquire the sound around the imaging device 200, and when the control circuit 204 is turned off, the audio acquisition device is prohibited from acquiring the sound around the imaging device 200. That is, the control circuit 204 allows the audio acquisition device to acquire the sound around the imaging device 200 when the baffle 205 is in the first position, and prohibits the audio acquisition device from acquiring the sound around the imaging device 200 when the baffle 205 is in the second position.

In the present disclosure, the audio acquisition device may include, but is not limited to, a microphone, etc.

Guide rails are provided on two sides of the panel 2011 on the main body 201, and the baffle 205 is movable between the first position and the second position by means of the guide rails, however, the present disclosure is not limited thereto, and any manner capable of moving the baffle 205 between the first position and the second position will be applicable to the present disclosure.

The panel 2011 may be provided with an imaging device icon (not shown in FIG. 2), and when the baffle 205 is in the first position, the imaging device icon is located behind the baffle 205 and thus is blocked by the baffle 205. When the baffle 205 is in the second position, the imaging device icon is exposed to indicate that the imaging device stops working. By observing whether the imaging device icon of the imaging device is exposed, the state of the imaging device can be easily determined.

The panel 2011 may be provided with an indicator light (not shown in FIG. 2) for indicating a working state of the imaging device 2000. If the indicator light lights up, it is indicated that the imaging device 200 works normally, and if the indicator light goes out, it is indicated that the imaging device 200 stops working. The indicator light is also controlled by the control circuit 204. When the control circuit 204 is turned on, the indicator light lights up, and when the control circuit 204 is turned off, the indicator light goes out.

The baffle 205 may be provided with a through hole at the top. When the baffle 205 is in the first position, the lens 202 is exposed from the central opening of the baffle 205, and the indicator light is exposed from the through hole, and when the baffle 205 is in the second position, the lens 202 is blocked by the baffle, and the indicator light is exposed from the central opening of the baffle 205.

By observing the indicator light, the working state of the imaging device can be easily learned.

According to the imaging device of the present disclosure, for an imaging device in a working state, when the baffle is moved to the second position, the control circuit of the imaging device may be turned off by triggering the switch, so that the imaging device stops working, thereby thoroughly enabling the imaging device to enter a privacy protection mode, and also avoiding the reduction of the lifespan of the infrared LED caused by unnecessary light emission. In addition, the baffle as a whole can transmit infrared light, which improves the aesthetic appearance of the imaging device.

For better understanding of the present disclosure, how the imaging device achieves thorough privacy protection, avoids the reduction of the lifespan of the infrared LED, and achieves the aesthetic appearance of the imaging device will be described below in conjunction with a camera having a night vision mode as a specific application of the imaging device.

As shown in FIG. 4, the switch triggering component 401 is a recessed portion provided on the back of the baffle 306, and the switch 304 is a wedge-shaped protruding portion fitting the recessed portion. When the recessed portion is engaged with the protruding portion, the movement of the baffle may drive the switch 304 to move, so as to turn on or turn off the control circuit.

The switch triggering component and the switch of the present disclosure are not limited to the above configurations. For example, the switch triggering component of the present disclosure may be a magnet piece which is embedded in or attached to the baffle and has a suitable size and shape, the switch may be made of a material containing iron, and the magnet piece may control turning on or turning off of the switch by means of magnetic attraction.

According to the camera having a night vision mode of the present disclosure, when the baffle moves to the bottom of the housing of the camera, the switch triggering component of the baffle triggers the switch of the main control circuit to turn on the main control circuit, so that the camera is in a normal working state. When the baffle moves from the bottom of the camera to the top of the camera, the switch triggering component of the baffle triggers the switch of the main control circuit to turn off the main control circuit, and the lens, the audio capturing device and the infrared LED of the camera are all prohibited from working, thereby thoroughly enabling the camera to enter a privacy protection mode, and also avoiding the reduction of the lifespan of the infrared LED caused by unnecessary light emission. In addition, the baffle as a whole can transmit infrared light, which improves the aesthetic appearance of the camera.

In the camera 300 having a night vision mode of the present disclosure, the baffle is made of a black infrared transmitting material, and when the baffle moves from the bottom of the camera to the top of the camera, the lens of the camera is blocked by the black baffle, which gives the user a sense of safety as the lens is blocked visually.

In the camera 300 having a night vision mode of the present disclosure, the portion of the panel 305 which can be exposed from the baffle 306 may also be set to have a predetermined color, for example, a red-orange color or another color having a warning function. If the color is completely exposed from the baffle 306, it is indicated that the camera 300 stops working, and enters a privacy protection mode, and if the color is completely blocked by the baffle 306, it is indicated that the camera 300 works normally.

In this way, the working state of the camera can be easily determined on the basis of the indicator light 307, the color of the panel, the position of the baffle, etc.

In the above camera 300 having a night vision mode according to the present disclosure, when the baffle 306 moves over the opening of the housing 301 to completely cover the opening, the switch triggering component triggers the switch 304 to turn on the main control circuit, that is, when the baffle 306 is in the first position, the switch triggering component triggers the switch 304 to turn on the main control circuit. When the baffle 306 moves over the opening of the housing 301 to expose the opening of the housing 301 and block the lens 302, the switch triggering component triggers the switch 304 to turn off the main control circuit, that is, when the baffle 306 is in the second position, the switch triggering component triggers the switch 304 to turn off the main control circuit. The baffle 306 moves between the first position and the second position to control turning on and turning off of the main control circuit.

However, the present disclosure is not limited thereto, and the baffle 306 may move between the first position, the second position and the third position. In this case, when the baffle 306 is in the first position, the baffle 306 blocks the at least one infrared LED 303, the lens 302 is exposed from the central opening 3601 of the baffle 306, the switch triggering component 401 triggers the switch 304 to turn on the main control circuit, and the lens can receive visible or infrared light. When the baffle 306 is in the second position, the baffle 306 blocks the at least one infrared LED 303 and the lens 302, the main control circuit is still in a turned-on state, and at this time, the at least one infrared LED 303 emits infrared light, the emitted infrared light is transmitted through the baffle 306 to irradiate an object within an imaging range of the camera 300, infrared light reflected by the object is transmitted through the baffle 306 which blocks the lens 302 to be received by the lens 302 for imaging, so that the camera 300 enters a night vision mode. When the baffle 306 is in the third position, the baffle 306 blocks the at least one infrared LED 303 and the lens 302, and the switch triggering component 401 triggers the switch 304 to turn off the main control circuit, so that the camera 300 is enabled to be in an electrically turned-off state.

The baffle 306 may also be a slider mounted on the camera 300, and is slidable between the first position, the second position and the third position.

Although the at least one infrared LED 303 is exemplified as an infrared light emitting part which emits infrared light, the present disclosure is not limited thereto, and any device capable of emitting infrared light may be used as an infrared light emitting part.
